The invention herein disclosed is applicable to any type of slicing machine for slicing foodstuffs, but is shown specifically as relating to a gravity feed machine.

The slicing machine of the present invention .comprises a supporting structure or main frame 1, Figs. 1 to 4, which is integrally cast of aluminum, cast iron or other suitable material. The main frame I includes an upstanding housing or casing part 2 in which a driving motor 3, Fig. 3, is mounted.

A knife box 4, Figs. 5, 12 and 13, is operatively supported on the motor casing 2 of the main frame I and supports the driving mechanism for a rotatively mounted Slicing knife 5, Fig. 5, which is inclined from the vertical. A food table 6, Figs. 1, 2, 5 and 6, is inclined, as shown in Figs. 1, 2 and 5, and is demountabl positioned. The food table is preferably V-shaped and is arranged perpendicular to the slicing knife 5 so that substance carried by the meat table will be fed by gravity to the cutting plane of the knife 5 for cutting slices from a piece of substance. The inclined V-shaped slicing food table is reinovably mounted on a bracket 1, Figs. 1 and 5, which is connected to a part 8 of a slide carriage 9, Fig. 6,

whereby the food table may be reciprocated in a rectilinear path. A gauge plate I0, Figs. 1, 2 and 7, is provided to gauge the thickness of slices to be cut from the substance by the slicing knife 5. A knife center plate ll, including a knife guard 12, Figs. 1, 2, 5, 27 and 28, is arranged within the concave face of the dished cutting knife 5, and covers a knife edge finger guard l3, Fig. 26. A slice deflector I4, Figs. 2 and 32, is arranged on one side of the knife 5 to deflect slices as they are cut to permit them to fall in stacked formation on the upper surface of a part of the main frame I. Knife sharpening mechanism is arranged within a knife sharpener casing l5, Figs. 1, 2 and 27, which is recessed in the knife box 4.

upon which the gauge plate in is slidingly mounted.

The table top part l6, Figs. 1, 2 and 4, of the main frame I acts as a slice receiving table top or tray to receive slices as they are cut consecutively. Also, this top or table I6 is adapted to receive removable individual trays upon which the cut slices fall. Instead of individual trays, sheets of paper may be used to receive the cut slices. This table top I6 is depressed somewhat, there being an upstanding rounded rib-like or ridge formation 41, Figs. 2 and 4, along the front edge of the frame (near the operator), and along the left-hand side of the machine. The left rib or ridge-like formation 41 extends to the front face of the frame motor housing and merges therewith, Figs. 2 and 4. The front ridge or rib 41 extends to the part of the frame which acts as the housing part 45 for the operating mechanism of the gauge plate In and merges with the said housing part. The recessed table top I6, therefore, is bounded on the front and on the left side by the continuous integral raised left rib or ridge 41. The recessed top I6 is bounded on the rear by the front 24 of the frame motor housing 2, and on the right by the upwardly extending raised formation 49, 4|. The round housing part 4042 and the part 45 act as the housing for the slide rod or bar 23 and for the operating mechanism of gauge plate I0, Figs. 5 and 8.

The depressed table top l6, of the main frame I is so configurated that the depressed part thereof extends rearwardly an appreciable distance beyond the center of the knife 5, Fig. 1, and to the right of the machine an appreciable distance beyond the lower edge of the inclined knife; also, an appreciable distance beneath the knife 5 and its guard. The depressed table top I6 is below both the right and left faces of the knife, Figs. 1, 5 and 7. The construction and arrangement of the depressed table or slice receiving tray part I6 is characterized by providing a depressed fiat table under and adjacent all operating parts so that cleaning cloths may be passed under, about and around all surfaces so as to clean thoroughly, easily and quickly all surfaces adjacent the operable parts, particularly the knife, and still prevent meat juices, scraps and parts from falling into or draining upon or into operable parts of the machine. The frame I is characterized, further, in having the parts constructed and arranged, and of such a contour and design, as to permit it to be cast as a single unit, thereby permitting easy, quick and economical manufacture.

Motor mounting 3 The motor 3 is adapted to be mounted pivotally or swingingly and arranged for easy and quick removal for replacement, repair and inspection. The motor 3, of the usual type, includes its ordinary casing 48, Figs. '7 to 11, and is held in its pivotally mounted position by a rod 49, Figs. 8-10, engaging a guiding or pivot hole 50, Fig. 3, in the slicing machine frame I, and by a single securing bolt 5| passing through a block 52 and threadedly engaging the housing 2, Fig. 3. The entire motor 3 may be removed by merely unscrewing the single bolt 5|.

A semi-circular strap 53, Figs. 3, and 8 to 10, encircles a part of the motor casing 48 between the front and rear ends of the motor. One end of the strap 53 is configurated or curled to form a hollow, relatively tubular eyelet part 54 through which the rod 49 is inserted. The extreme end 55, Fig. 10, of the tubularlyformed part 54 of the strap 53 is slightly spaced from the outer surface of the strap 53, Fig. 10, so as to receive slidingly the deformed, crimped, or substantially triangular bead 56 on the end of a flexible metal encircling band 51. The deformed end or bead 56 is formed by bending the band 51 near, or at one end, as shown more specifically in Fig. 10. The end 56 of the band 51 is slipped into the space between the curled end and the main body of the band 53 whereby the crimped end 56. will be located inside of the tubular or eyelet part 54, causing they hand 51 to be locked removably to one end of the strap 53.

The other free end 59 of the band 51 is bent over upon itself to form a stirrup-like part 59, Figs. 7 and 9, which provides a hollow part 69 to receive securing bolts 6|. The ends of the band are welded or otherwise secured together as indicated at 62, Fig. 9. The heads of the attaching bolts 6| are arranged in place before the part 59 is deformed into stirrup-like formation, there being spaced holes provided in the end of the stirrup-like part 59 to permit the threaded shanks or stems of the bolts 6| to pass, Fig. 9. The shanks of the bolts 6| pass through holes in the outer end of the strap 53, and nuts 63 tighten the band 51 and the strap 53 about the motor casing 48. The strap 53 and band 51 provide a supporting hanger for the motor 3, Fig. 9.

The motor is hung pivotally or swingingly by means of the aforesaid rod 49 and the bolt 5|.

One end of the rod 49 passes through the guiding or pivot hole 50, the other end of the rod 49 carrying the block 52 which is fixed thereto in any desirable manner such as by a pressfit, or by welding. This block 52 has a smooth hole therethrough through which the bolt 5| passes, the bolt 5| being received threadedly in a threaded hole in the machine frame, Fig. 3. The rod 49 is loosely mounted, that is, mounted so as to permit revoluble or oscillatory movement-in the curled or eyed tubular end part 54 of, the strap 53, whereby the entire motor is suspended pivotally inthe frame and movable about the rod 49. This pivotal mounting of the motor permits the motor to act as a belt-tightener inasmuch as the weight of the motor may bear on the belts 64 which are trained over the pulleys or sheaves 36, 31 on the shaft 38 of the motor 3, Figs. 3 and '7.

A leaf spring member 65, Figs. 3 and 8, in the form of a piece of flatspringy metal, is adapted further to act as a belt-tightener. This leaf spring 65 is secured in relatively fixed position with respect to the motor by the same bolts 6| which secure the stirrup end of the band 51 to the strap 53, Figs. 3 and 8. The leaf spring has holes therethrough to permit the shanks of the bolts 6| to pass, nuts 66, Figs. 3 and 9, being provided to lock the leaf spring 65 in position against the outer surfaces of the first mentioned nuts 63. The free end 61 of the leaf spring 65, Fig. 8, is adapted to be sprung or flexed under a projection 68, Fig. 8, on the main frame, thereby providing a tension or urging action on the leaf spring 65. This urging or spring tension of the leaf spring 65 tends to urge springly the motor 3 in a direction so as to tension further the belts 64, thereby providing belt tightening means. The weight of the motor 3, having pivotal movement in a restricted arcuate path, and the leaf spring 65
